Abstract

A greenhouse framework comprises arcuate members connected to longitudinal members to form a tunnel. Each arcuate member is formed of a number of elements which are joined to the longitudinal members by a jointing element. The frame members are of round or rectangular section tubing with rounded corners. A jointing element (3) comprises a rectangular tube (3a) with rounded corners and a depression (3a4) along the middle of its lower side. Tube (3a) is welded to a round tube (3b) or to a similar tube but inverted, and at right angles. The four ends of the tubes of the jointing element constitute spigots over which the ends of the frame members are pushed.
